(GRANTED UNDER THE rRovIsIeNs erA Ter ACT-or nance'. s, 1921, 41 STAT. 1.., 1313K)y To @ZZ whom t may 'concer/n.' Be it known that we, JOHN FRANCI WI-rr n and l/VILLIAM l-loLLnrnN 1WTE-irre, sub

jects of the King of Great Britain, residing inBradford, in the county of York and- Kingdom of England, have invented certain new `and useful Improvements in Vool- /Vashing Machines, for which we have filed an application in England, October 8th, 1919, Patent No. 162,313, of which the following isa specieation.

The present invention relates to improvements in wool washing machines, for the removalof fatty matter, dirt, sand, vegetable matter' and the like from wool.

lt has been usual to wash wool in a machine consistingof along bath in which the wool is forked by a series of reciprocating prongs progressively onwards through the bath.

According to the present invention, wool is arranged to be passed through the scouring bath in a pathsimilar to a series of cusps.

This may be obtained by providing a false bottom for the washing vessel consisting of a number of perforated semi-circular or the like curved parts in sequence over which the wool is passed by any desired means but preferably by drums having tangential sur faces thereon revolving coaxially withl the said concave false bottom parts.`

The invention is more particularly described with reference to the accompanying drawings in which i Figure 1 is an outside elevation of one form of construction.

Figure 2 is a corresponding end view- Figure 3 is an enlarged view of one of the drums.

The wool washing machines comprises a vessel 1, provided with a false bottoni consisting of a series of perforated semi-circular or the like curved plates 2, 3, 4, 5, in sequence. Cencentijic with these curved plates, revolve rotary drums or cylinders 6, having a plurality of tangential beaks 7, of wedge shape, which beaks are consecutively formed with circumferential parts of the said drums. By this means the wool is fed progressively forwards through the ina-- chine by the ends of the tangential beaks and owing to the shape of these, there is no tendency for the wool to lap round them but this is taken up by one drum as it leaves the j i rollers.

Vthrough the machine it moves in a number of semi-circular or other curved paths end to end formed of a plurality of semi-circu lar false'bottoms 2, 8, 11,5,` etc."` arranged above the bottom of the vat or vessel 1, which is of pyramidal shape as shownat 9.

1t is preferred to divide the bottom of the vessel up into a number of compartments (two in the instance shown) so that the accumula-ted dirtin the bottom of any part can be drawn off separately.

The drums 6, are mounted on a frame suspended by cables 13, from pulleys 14, on brackets 15, on the main frame of the machine so that by operating the'handle 16, the pulley over which the cables 13, are wound, can be turned in either direction, to raise or lower the drums from the vessell, or in certain cases it may be desirable to use `this means to adjust the spacing ofthe beaks of the rollers from the false bottoms 2, Y

e, i, 5, ac. v

It will be usually desirable to provide some stop motion to prevent the lifting of the rollers too far upwards. This may be any mechanical form of device desired.

As the wool leaves the machine, it is subjected to a water spray 18. This has the effect of moving the wool into the path of the squeeze rollers 19, and further of washing back the dirt which will be squeezed out of the wool as it is passed through these The squeezing pressure of these rollers is adjustable by screw and leverr mechanism such as 26, 27 and 28.v

After leaving the squeezing rollers the wool is subjected to a beater such as 21 which may be 0f the form shown in Fig. 3,l

ing machine to a drying ljmechanism as usual.

The use of an operating drum between a paifrof washing machines in tandem is found to give verydeslrable results as the.

25, three or more of such ortions. being arranged round the roller uas" slioivn.

DWe declare that what We claim is 1,-

n. l, A vvol machine. c'oinprising in conbinatioii, vatto contain liquer, a tray disposed therein so as to be submerged beneath the vvafshin'g liquor fomned of a sequlene OfSmcyldical perforated Suorfaces, a plurality of rotatable drunu's provvith solid Vfaced beaks andv spaced @gaat Se that aie bears atefeofar out of contact with eaeh other during the revolution of said druins, said beaks rotating in to the (lindrical surfaces of the tray.

2. AI Wool` Washing machine eomprising in combination, a vat te contain liquor, provided with a bottom formed With a plurality of recesses of Substantial inverted pyramidahshape, ymeans for draining each `recess separately, a tray disposed above said recesses in said vat and submerged beneath .the Washing` liquor formed of a sequence of semi-cylindrical, perforated surfaces, and a sequence of rotatable'druins Adisposed one over` each surface and provided With solidfaced beaks rotating in proiiinity toeach surface. n
